Mechanical Seals

When it comes to quality mechanical seals, Dichtomatik offers some of the most affordable and effective sealing solutions on the market today. However, you might be wondering precisely what purpose they serve and what applications they’re used in, so we’ve collected some insight for you below.

Let’s take an in-depth look at mechanical seals, their uses, and how they can benefit you!

What Exactly Are Mechanical Seals?

Before diving into the details, it’s important to have a basic understanding of what mechanical seals are. In the simplest of terms, mechanical seals are used to contain fluid flowing through a vessel where there’s a rotating shaft or housing component that needs an airtight seal. Often, mechanical seals are used in things like pumps or mixers that have a rotating shaft that travels from an area where there’s liquid into a dry machine component. Mechanical seals are used to prevent any pressurized liquid from entering this dry area.

What Are Some of the Most Common Applications and Industries?

Mechanical seals are designed for a variety of different applications and industries including central heating, refrigeration, and irrigation systems, food, beverage and dairy applications, pumps and mixers, as well as light fluid duties.

Mechanical Seal Styles

The team from Dichtomatik offers a variety of sealing solutions and standard mechanical seal types, such as:

PTFE Wedge Seals: This type of seal is designed for use with corrosive chemicals. The wedge seal is ideal for a wide range of applications and offers added performance due to its O-ring alternative design and the range of elastomers available for it.

Balanced Diaphragm Seal: Most suitable for rotary equipment, balanced diaphragm seals offer great solutions for compressors, pumps, and mixers. Common applications for these pump types include chemical, petrochemical, water, food processing, and other duties.

Conical Spring Seal: Due to its wide O-ring and face materials, conical spring seals are well-suited for rotary shaft equipment like agitators, compressors, pumps, and mixers.

Elastomeric Bellows: Due to their robust design and non-clogging features, elastomeric bellows are best suited for hygienic applications or ones that contain solid material. They’re also easily customizable and can be adapted to suit any length and housing configuration.

Parallel Spring Diaphragm Seals: This seal family is a great sealing solution for applications like food processing to water services. They’re widely used in everything from pumps to compressors and are ideal for nearly every type of rotary machine.

Parallel Spring O-Ring Mounted Seals: Commonly used in marine-pump applications, parallel spring O-ring mounted seals also provide effective solutions for pulp and paper, textile, refrigeration, and waste treatment applications as well.

What Are the Benefits of Mechanical Sealing Solutions?


Now that you know a little more about how mechanical seals work and some of the most common seal types, it’s important to learn about the primary benefits the right sealing solutions can offer to your applications.

Some of the most attractive benefits of mechanical sealing solutions are:

  • Modern designs won’t damage pump shaft or sleeve.
  • Self-adjusting seal springs reduce the need for daily maintenance.
  • Reduced bearing contamination.
  • Less corrosion due to fluids being contained in the pump.
  • Less product waste or leakage.
  • Airtight vacuum seals.
